Probably a Tektronix 4132. These were UNIX workstations based on the
National 32016 CPU, running a derivative of Berkeley 4.2 UNIX. The
4132 had a built-in Wangtek QIC-24 drive, with a special interface board
(QIC-24 on one end, and SCSI on the other end) made by Adaptec that
allowed the drive to sit on the built-in SCSI bus.
These drives would use DC300-A tapes. I believe that DC600's would also
work, but there were occasional issues with the tapes getting tangled
because of the much thinner tape in the DC600 cartridges.

The drive I have is a Wangtek 54590, circa 1983 and the head
assembly is definitely on a stepper. I wonder what piece of
Tek gear it's from then?
